Abstract
High strength and low gas permeability cellulosic composites were produced using the papermaking technology with a commercial microfibrillated cellulose MFC The effect of blending MFC with hardwood fibers was compared to the direct refining of the fibers with and without polyamideamineepichlorohydrin PAE addition The addition of MFC free or tethered to pulp fibers combined with PAE can increase the dry strength and wet strength of cellulosic materials by an order of magnitude Air permeability of the composites decreases by up to orders four of magnitude with MFC addition The hypothesis that refining wood fibers can produce tethered MFC which provides equivalent strength properties but significant drainage benefits was proven Furthermore major benefits in paper formation uniformity fiber distribution homogeneity were achieved with refined fibersThe financial contribution of Australian Research Council LP0990526 Visy and Nopco paper technology is acknowledged The authors would like to thank Misses Sigappi Narayanan and Hui Hui Chiam for experimental assistance and Mr Swambabu Varanasi for SEM expertise
